Frequently Asked Questions

Should I just replace the cylinder?

If the bore is pitted, yes. If it is smooth, the seal kit restores it. Bleed the brakes afterward either way.

How do I know the wheel cylinder is leaking?

Pull the drum and peel back the wheel-cylinder boot; fluid behind the boot or a wet backing plate means it is leaking. A soft pedal with no external line leak is the on-road sign.

Do I need to bleed the brakes after this job?

If you open the hydraulic system, yes - bleed it and confirm a firm pedal before driving. If no hydraulic line is opened, no bleeding is needed.
